The company's tech staff is 83% male, with roughly similar ethnic breakdown. And leadership of the company is 79% male and 72% white.

According to a company filing, Google(GOOGL) had 47,756 full-time employees at the end of 2013: 18,593 in research and development, 15,348 in sales and marketing, 6,563 in general and administrative, and 7,252 in operations.

Civil rights activist Jesse Jackson has recent focused on minority hiring at U.S. tech companies, appearing at shareholder meetings of both Google and Facebook(FB).

"Silicon Valley has a long way to go," he said at the Google meeting. "If Google can build cars that can drive themselves, it can certainly build a pipeline to bring African-Americans and Latinos ... into this changing technology world."

Jackson requested that Google and other tech companies release their diversity data. At the Google meeting, its Chief Legal Officer David Drummond announced it would do so by June, saying the company had decided it had been wrong to withhold the data from the public.
